Welcome to a laptop battery specialist of the dell laptop battery
The large, button-free, multitouch click pad should be a familiar sight by now. This version works well with multitouch gestures, such as two-finger scrolling, and is about as responsive as you're going to find, save for Apple's MacBooks. Both the keyboard and touch pad seem to be the same as those found on the XPS 14. On that smaller laptop, both were a better fit. Here, both could stand to be bigger.
One area where the XPS 15 beats the XPS 14 (and many other 15-inch laptops as well) is screen resolution. For a premium 15-inch laptop, the 1,920x1,080-pixel resolution is entirely appropriate, and I'd expect nothing less in something that costs $1,299 and up. Having a 1080p screen can be a bit overwhelming on a 13-inch laptop, and it's a matter of taste for 14-inch models (the XPS 14 we reviewed had a 1,600x900 display). The screen itself was bright with battery like dell Inspiron E1505 battery , dell Inspiron 1501 battery , dell GD761 battery , dell KD476 battery , dell TD347 battery , dell Inspiron 1000 battery , dell Inspiron 2200 battery , dell 312-0292 battery , dell INSPIRON 2600 battery , dell INSPIRON 2650 battery , with edge-to-edge Corning Gorilla Glass over it, but very, very glossy, picking up a lot of glare from nearby lights.
The right edge of the system is dominated by a slot-loading optical drive, along with headphone and mic jacks and an SD card slot. The left side has all the USB and video-out ports, including both HDMI and DisplayPort outputs. All three USB ports are of the 3.0 variety, and one of them supports the charging of USB-connected devices while the laptop is off or asleep.
The least expensive XPS 15 configuration starts at $1,299, and includes an Intel Core i5-3210M CPU, an Nvidia GeForce 630M GPU, and a 500GB hard drive/32GB solid-state drive (SSD). This $1,699 configuration trades up to a Core i7-3612QM and a GeForce 640M GPU, plus a 750GB HDD/32GB SSD. It also includes a Blu-ray drive, which is a step up from the basic DVD burner in the base model.
In our benchmark performance tests, the Dell XPS 15 matched up well against other midsize quad-core Core i7 laptops with Intel's current-gen Ivy Bridge chips. This is the top CPU choice for this particular system. The 15-inch Maingear EX-L 15 can use the top-of-the-line Core i7-3820QM for faster scores, but it also costs around $500 more. A closer comparison, the Lenovo IdeaPad Y480, was also a bit faster (and around $500 less).
At this level, however, the differences in benchmark performance are largely academic. Any of these laptops would be more than fast enough for any task you'd throw at them, from HD video rendering to Photoshop to running high-end games.
The included Nvidia GeForce GT 640M graphics card in this system isn't the top of Nvidia's laptop line, but it's a solid midrange part (whether you should expect more than "midrange" in a $1,699 laptop is another story, however). In our very challenging Metro 2033 test at full 1,920x1,080-pixel resolution, the XPS 15 ran at 20.3 frames per second, which is considered an excellent score on that test. The more forgiving Street Fighter IV test at the same resolution ran at 73.1fps.
